Question

In the figure, which pair of angles represent the adjacent angles?

• A. ∠1 and ∠3
• B. ∠5 and ∠7
• C. ∠1 and ∠4
• D. ∠6 and ∠8

Answer 1

The correct option is C ∠1 and ∠4


Adjacent angles are two angles that have a common side and a common vertex but do not overlap in any way.

Here,
∠1 and ∠4 have a common vertex O and a common side.

∴ The pair of angles ∠1 and ∠4 are adjacent angles.
